Elements and Performance Criteria

  1. Determine technical drawing requirements.
  2. Select techniques.
  3. Produce technical drawings.

Required Skills

Required skills

literacy skills sufficient to interpret material required to produce technical drawings

numeracy skills sufficient for calculations and measurements required to produce technical drawings

Required knowledge

physical properties and capabilities of the range of materials tools and equipment used for technical drawing work

knowledge about technical drawing techniques and their application to a range of contexts and subject matter

technical drawing practices their history and theory

awareness of copyright moral rights and intellectual property issues and legislation

organisational and legislative occupational health and safety procedures in relation to technical drawing work

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The following evidence is critical to the judgement of competence in this unit

production of technical drawings which show a command of the selected techniques and meet the required purposeobjectives

knowledge of technical drawing techniques and their application to specific contexts

Context of and specific resources for assessment

The assessment context must provide for

practical demonstration of skills using required materials tools and equipment to produce technical drawings consistent with the conceptwork requirements

Method of assessment

Assessment may incorporate a range of methods to assess performance and the application of essential underpinning knowledge and might include

direct observation of the drawing in progress

evaluation of technical drawings produced by the candidate

questioning and discussion of the candidates intentions and work outcome

review of portfolios of evidence

third party workplace reports of performance by the candidate

Assessment methods should closely reflect workplace demands eg literacy and the needs of particular groups eg people with disabilities and people who may have literacy or numeracy difficulties such as speakers of languages other than English remote communities and those with interrupted schooling

Assessment of this unit requires access to the materials resources and equipment needed to produce technical drawings
